“…Intramolecular heterocyclization is the main reaction in the case of all of the investigated primary and secondary alkenols, while tertiary alkenols, under the same experimental conditions, are converted into cyclic products not at all by PhSeBr and in only small amounts by PhSeCl. On the other hand, in the presence of some Lewis bases (triethylamine, pyridine, quinoline, 2,2′-bipyridine) and Lewis acids (SnCl 2 , CoCl 2 , Ag 2 O, AlCl 3 , FeCl 3 ) all of the alkenols (primary, secondary, and tertiary) cyclized in excellent yields with both reagents …”

“…As a part of our ongoing research, directed toward the intramolecular cyclization of unsaturated alcohols by means of phenylselenenyl halides as reagents, we have examined the chemo-, regio-, stereoselectivity and reaction kinetics as a function of substitution pattern at the double bond and at the carbinol carbon atom of the used alkenol substrate. The influence of some Lewis acids and bases as catalysts on mechanistic pathway and reaction rate has also been evaluated [12][13][14][15][16][17][18][19][20][21].…”

“…During recent years, there has been some investigation of the cyclization reactions of alkenols in the presence of some additives, which influences the increases of the yield of cyclic ether product [17,21,22]. The base mediated cyclizations have been much less studied, but in recent years some results has been achieved [15][16][17][18][19].…”
